A 3-day workshop led by researchers from the Universities of Portsmouth, Southampton, Sussex, Hertfordshire and Surrey, comprises five pedagogic sessions exploring different aspects of cosmology and gravitation through a mix of lectures, seminars and tutorials.

Theory Overview: This session asks what we can expect to learn in the decade 2020-2030. It provides a context to explain how concrete measurements might get turned into knowledge about the underlying physics. It explains the framework used to interpret cosmological measurements. Topics covered include modified gravity, structure formation measurements, inflationary initial conditions and the cosmological constant problem.

Gravitational waves: The newly-emerging field of gravitational wave astronomy will be discussed in the context of detectors, sources and cosmology.

Universe of Galaxies: This session will focus on how galaxies can be used to place constraints on cosmology, specifically the use of galaxies to measure dark energy through baryonic acoustic oscillations and supernovae, gravitational lensing to probe the distribution of dark matter, and ‘near field’ cosmology to explore the conditions of star formation in the early Universe.

Cosmic Microwave Background: This session will cover the CMB power spectra, polarisation and B modes, and CMB lensing.
